Installation

Only special-purpose parts can be used for installation of the heater. Following picture is the diagram forinstallation. The positions and ways of fixing of various parts may vary from one automobile model to another, butthe general principles must be followed in conformity with the requirements of this chapter. Otherwise the heatermay not work normally or safety problems my occur.

Main heater installationThe main heater could be installed both inside and outside of the vehicle. If the heater is installed outside the

vehicle, measures must be taken to avoid splashing water onto the heater. Enough space must be provided forinstallation for the convenience of heating air flow and installation,maintenance of the main heater.

Good sealing is necessary between the main heater and the installation surface on the vehicle.The special gasketsupplied by the manufacturer must inserted in.And the installation surface must be even.Its parts at the installationbases of the main heater should have uneveness less than1mm.After drilling installation holes, eveness must beimproved according to this requirement.At installation, please rotate the four M6 nuts tight, which are provided bythe manufacturer.

For re-installation of the main heater, a new gasket must be used to replace the old one.

Attention must be paid to that the inclination angle shall not exceed the limit, or normal operation will beaffected. Direction for installation of the main heater is shown in the following picture.

After installation of the main heater,please check and make sure that there is no contact or friction between theblade wheel of fan and other nearby parts to avoid unsmooth operation.Installation of Air Heating System

The air heating system of the heater should not be connected with the air channel of the vehicle.Eitherindependent outer circulation or inner circulation mode can be adopted.

When an external heating air tube is attached to the heater, the tube diameter should not be smaller than

85mm.Its material should be capable to resist temperature of 130℃。The maximum pressure drop between the air inlet side and outlet side of the air heating system should not be higherthan 0.15kPa.

The hot air from the heating system should not erupt onto such parts which are unable to resist heat.Inpassenger vehicles,the hot air vent should not be blocked by passengers.A self-provided protective net can beinstalled if necessary.For heater working in external circulation mode,the position of air inlet port should be proper to guaranteed thatunder normal operation no splash of water can be sucked into the heater the no exhaust from the engine can besucked in.

For heater working in internal circulation,measures should be taken to avoid re-entering of the supplied hot airinto the air inlet port.If no air inlet tube is attached in this mode,an air inlet hood with grids must be installed at theair inlet port of the main heater.The inlet air should be drawn from the cold area of the compartment,such as underthe seats or berths.

Installation of Fuel Supply SystemFuel for the heater can be supplied from the fuel tank of the vehicle or an additional independent fuel tank. It is

not allowed to install the fuel tank in the cab or passenger compartment or any region that is possibly to cause fire ifan independent fuel tank is used.

The elevation difference between the heater and fuel pump, and between the fuel pump and the fuel pumpproduces pressure from fuel to the fuel pump.The inner diameter and length of the fuel tube is related to theresistance of the fuel route.Please consider such factors for installation.

Fuel pump installationThe fuel pump should be installed in places that can avoid heat radiant from the vehicle parts that can emit heat

and in places with cool air.Its ambient temperature should not exceed 20℃ . Directions of installation of the fuelpump are shown in the following picture. When installing the fuel pump, please use the fuel pump holder suppliedwith the heater to hold the pump tight. The pump is fixed with the shock-reducing tightening piece.

Fuel Filter installationThe fuel filter should be installed before the fuel inlet port.Please make sure that the fuel flow is correctly

followed. Its position shall be in conformity with the above picture.

Installation of Fuel TubeOnly the flexible nylon tube, which has good light-resistance and thermal stability ,supplied with the heater can

be used as the fuel tube. The inner diameter of the tube is Ø2mm.The position of fuel tube should be against flying stones and be away from any heat emitting parts of the vehicle.

Protective device can b installed if necessary.The fuel tube from the fuel pump to the main heater should be in any directions other than downward direction.

The fuel tube shall be tied in some proper location to make it fixed. The distance between two ties shall be less than50cm.

The fuel tube fittings supplied with the heater should be used for connections between fuel tube and fuelpump,fuel tube and heater,fuel tube and sucking tube of fuel tank and fuel tube and reducing T.The fuel tube shouldtie with fuel tube clamps.Bubbles should be eliminated from the connecting places.

Installation of Fuel Taking DeviceThe openings on the fuel tank (or tank cover)for installation should be appropriate in size,with trimmed brim

and with good eveness around the opening.Good sealing is necessary for the base of the fuel taking tube.The bottomend of the fuel taking tube should be 30mm-40mm from the bottom of fuel tank to suck enough fuel and at thesame time to avoid sucking in impurities sediment on the bottom of fuel tank.

If fuel is taken from the fuel pipe to the engine,the fuel pipe from the fuel tank to the fuel filter should bedisconnected and re-connected with the thicker pipes of the reducing T.And the thinner pipe of the reducing Tshould connect the fuel pump of the heater via fuel tube fitting and tube. The angle of installation must inconformity with following picture, or normal work of the heater will be affected.

After installation, the vehicle engine shall be started and then turned off after one minute’s work to eliminateair trapped in the fuel sucking pipe.

Installation of Electrical System

Installation of Combustion Supporting Air Sucking Tube and Exhaust Discharge Tube

The combustion supporting air must be sucked in from external fresh air outside the vehicle.The exhaust fromcombustion must be discharged into the air through exhaust tube. Measures must be taken to avoid the exhaustfrom re-entering he vehicle.

The tubes go through the outer wall or holes on the bottom of vehicle.Measures must be taken to prevententering of splash water. The tubes must be protected and can resist shock permanently.

Only the air inlet tube and exhaust tube provided with the heater can be used. The air inlet tube is a corrugatedpipe made of a aluminum tube that it’s surface is covered by plastic and paper: The exhaust tube is corrugatedstainless steel tube. Please identify them and do not make mistake st installation. To connect them with heater,please use the supplied clamps to fix them tightly on the combustion supporting air inlet and exhaust tube ventrespectively. The protective hood on the vents of the air inlet tube and exhaust tube must be kept in good condition.Do not damage them or remove them.

Both the air inlet tube the exhaust tube should come outwards and downwards from the heater, otherwise aØ4mm hole shall be prepared at the bottom of the tube for discharge of condensation water. If the tube need curve,the radius cannot be smaller than 50mm.Also, the sum of all curve angles for each tube shall not exceed 270℃.

The opening of the tubes should not be opposite to the direction of the running vehicle.The tube openings should not be blocked by slurry,rain and snow or other dirt.The exhaust tube should be installed in far distance from the plastic parts or other objects with poor thermal

resistance of the vehicle body.The exhaust tube should be properly fixed.The exhaust vent should bedownwards,perpendicular to road surface with angle of 90°±10° .To ensure such an angle,the fixing clip for theexhaust tube should be within 150mm from the tube end.

Warning: Violation against the above requirements may cause fire.If the section of the exhaust tube inside the vehicle may be touched by passenger,a protective cover has to be

installed to prevent human contact and scald.
